http://techgeeks.co.nr/ Windows XP is much better at handling high-speed Internet connections than the “made for dial-up” Windows 98, but there is still one little tweak that can increase your connection speed. The following tweak only works with Windows XP Professional:

-Click Start, Select “Run”
-Type “GPedit.msc”
-Expand the “local computer policy” branch
-Expand the administrative templates” branch
-Expand the “network branch”
-Highlight the “QoS Packet Scheduler” in the left window
-In the right window, double-click the “limit reservable bandwidth” setting
-One the setting tab, check the “enabled” item
-Where its says “Bandwidth limit %,” change it to read 0
-Close out of the window and reboot to make the new settings active.

What it Bandwidth:
The term bandwidth has a number of technical meanings but since the popularization of the Internet, it has generally referred to the volume of information per unit of time that a transmission medium (like an Internet connection) can handle.

Its use:
In electronic communication, bandwidth is the width of the range (or band) of frequencies that an electronic signal uses on a given transmission medium. In this usage, bandwidth is expressed in terms of the difference between the highest-frequency signal component and the lowest-frequency signal component. Since the frequency of a signal is measured in hertz (the number of cycles of change per second), a given bandwidth is the difference in hertz between the highest frequency the signal uses and the lowest frequency it uses. A typical voice signal has a bandwidth of approximately three kilohertz (3 kHz); an analog television (TV) broadcast video signal has a bandwidth of six megahertz (6 MHz) — some 2,000 times as wide as the voice signal.
2) In computer networks, bandwidth is often used as a synonym for data transfer rate – the amount of data that can be carried from one point to another in a given time period (usually a second). This kind of bandwidth is usually expressed in bits (of data) per second (bps). Occasionally, it’s expressed as bytes per second (Bps). A modem that works at 57,600 bps hastwice the bandwidth of a modem that works at 28,800 bps. In general, a link with a high bandwidth is one that may be able to carry enough information to sustain the succession of images in a video presentation.

It should be remembered that a real communications path usually consists of a succession of links, each with its own bandwidth. If one of these is much slower than the rest, it is said to be a bandwidth bottleneck.
